Nutrient conditioner for acidified soil in orchards, and preparation method

Abstract

The invention discloses a nutrient conditioner for acidified soil in orchards, and a preparation method and applications thereof. The conditioner comprises the following components in portions by weight: 5-10 portions of fly ash, 5-10 portions of furnace slag, 50-70 portions of calcium cyanamide, 0.5-1.0 portion of urease inhibitor, 10-20 portions of light burning powder, 5-10 portions of common calcium magnesium potassium phosphate, 3-5 portions of zinc oxide and 5-8 portions of refined bentonite. The preparation method of the invention is simple, and the conditioner is suitable for conditioning acidified soil in most orchards such as apple orchards, pear orchards and the like and can enhance the utilization efficiency of fertilizers; the conditioner can also be used as a carrier for producing microbian soil conditioners or producing organic fertilizers by fermenting with organic substances to increase the population quantity of microorganisms beneficial to soil; and the conditioner can obviously enhance the fruit output, improve the fruit quality and strengthen the disease resistance.

Description

technical field [0001] The present invention relates to an orchard acidified soil improver with disinfection effect and its preparation method and application, in particular to an alkaline mixed mineral soil improver using medium elements as the main nutrition and its preparation method and application, belonging to nutrient soil improvement technology field. Background technique [0002] Entering the 21st century, my country's agricultural industry structure has undergone tremendous changes. The open-field fruit tree cultivation system has developed rapidly and achieved good economic and social benefits. The fruit industry has also become the most internationally competitive field in my country's agriculture. Its development not only greatly meets the needs of improving people's living standards, but also has become an important means to transform traditional agriculture and move towards modern agriculture. However, while people have benefited from orchard production in re...

Problems solved by technology

But lime also has its disadvantages, it has much less effect on the acidity of the underlying soil than the top layer

A large amount or long-term application of lime will not only cause soil compaction and form "lime board field", but also cause the imbalance of the three elements of soil calcium, potassium and magnesium, resulting in reduced production

[0005] Existing acidified soil improver patents and other technologies can not effectively improve the acidified soil in orchards, as Chinese patent document CN 1928000A (application number: 200610068864.2) discloses a soil improver, although it can increase soil temperature, Improve the soil aggregate structure to achieve the purpose of improving soil, increasing crop yield, and optimizing product quality, but it also brings in acid radical ions while regulating the soil, which has no good effect on reducing soil pH, especially in orchards with severe acidification

Chinese patent document CN 1948429A (application number: 200610146026.2) provides a special nutritional soil improver for saline-alkali land, although it can simultaneously improve the physical and chemical properties of the soil, suppress the increase in salinity, neutralize the alkalinity of the soil, and provide crops with rich Nutrients, but its pertinence is not strong, and the nutrients it contains are mostly organic substances. There are no positive reports on the improvement of acidified soil in orchards and the improvement of comprehensive nutrition of trees.

[0006] As mentioned above, although there are many inventions of soil amendments including acidic or saline-alkaline soil amendments, most of them are concentrated on the soil of field crops such as grains, or although most of the nutrients are included, they are used for acidified orchard soil improvement. , there is no more targeted invention and innovation to better reduce the pH value of the soil
